uv Package Management Assistant

Quick start

• Use uv for all Python dependency tasks; do not use pip, pip-tools, or poetry.
• Add or upgrade with uv add <package>; remove with uv remove <package>.
• Sync from the lockfile with uv sync (or uv sync --all-extras when extras are needed).
• Run scripts with the right env using uv run <script.py> and manage script-specific deps via uv add/remove --script.
• See references/uv_rules.md for full command guidance and script metadata examples.

Workflow

1. Manage project dependencies

   • Add/upgrade: uv add <package>
   • Remove: uv remove <package>
   • Resync from lock: uv sync (or uv sync --all-extras to include optional deps for development).

2. Run apps and scripts

   • Execute with uv run <script.py> to ensure dependencies are resolved.
   • Manage script-only deps with uv add --script <script.py> <package> or uv remove --script <script.py> <package>.

3. Inline script metadata

   • Optionally define script requirements inline (see reference).
   • Reinstall script deps from lock with uv sync --script <script.py>.

4. Do not

   • Avoid pip install, pip-tools, poetry, or mypy's install-missing-libraries prompts. Stick to uv.
